Hi cparrapa. thanks for such a great project!!I've managed to print and assemble Otto ( which was easier than I thought it would be). I've even managed to load up the code for smooth criminal and its been dancing all over my desk!! However, I'm a complete novice when it comes to code/ programming (especially Arduino). How do I change modes/ upload new code?? I've tried uploading the avoid code, but I get error messages and Otto just keeps on dancing!!Please forgive my ignorance, but any advice would be greatly appreciated!!Ian
